Application filed July 31, 1915. Serial No. 42,951.

To all whom it may concern:

Be it known that I, RICHARD JAMEs FRET- TIE, a citizen of the UnitedStates, residing at Jamaica, in the county. of Queens and State of NewYork, have invented certain new and useful Improvements in Sound- Boxes,of which thefollowing is a specification.

My present invention relates to improvements in sound-boxes andcomprises improvements whereby the sound-box is adapted to be convertedto play either lateral or vertical wave records. The features andadvantages of' my improvements will be apparent to those skilled in theart from an understanding of the following description in connectionwith the drawings.

lln the latter Figure 1 is a face-view of a sound-box illustrating oneform or embodiment of my improvements shown as if playing a lateral-wavedisk-record; Fig. 2 is a partial edge view of the sound-box in Fig. 1;Fig. 3 is similar to Fig. 2 except that it shows myfdevice adjusted asif to play a vertical wave disk record;. Fig. 4 is an en-' larged veoical section partly in elevation on the line 44 in Fig. 2 looking inthe direction of the arrows; Fig. 5 is a modificati'on, the View. beingotherwise similar to Fig.

.4; and Fig. 6 is a side view of,one of the parts in F1g. 5.

I will now describe the specific devices of the drawings: 1 is thecasing, of the soundbox and 2 the diaphragm. The stylus bar comprises anupper part 3 and a lower part 4, said parts being pivoted to each other,so that the lower part can be adjusted either to extend in continuationof the upper part as in Figs. 1 and 2 for playing lateral wave records,or to extend transversely to the up per part as in Fig. 3 to playvertical wave records.

One end of the part 3 is attached to the diaphragm whereas the other endhas transverse oppositely directed cylindrical extensions or trunnions3, in whose ends are formed suitable centers or bearings for the pointsof the pivot-screws 5 which are tapped into and extend through thestationary lugs 6 on the casing 1 of the sound-box. The end 7 of eachscrew may be slotted, to enable said screws to be adjusted by a screwdriver in the lugs 6 to form ivotal bearings for the stylus bar tooscillate upon; .see Fig. 2.

jacent the space between the lugs, both of them are bored so as toreceive the trunnions 3 through them whereby the lower part 4 of thestylus bar can 'be pivoted as aforesaid into and out of the positionsshown in Figs. 2 and 3. When the part 4 has been adjusted intothe-desired position,

' the screw 8 is tightened with the result that the lugs 4 and 4' arecaused to clamp against the larger-portion 3 of the stylus bar fromwhich the trunnions 3 project, the net result being that said lower andupper parts of the stylus bar are now rigidly united and will act as onebar or lever in the playing of the records, the pivoting of theentirebar being on the points of the pivot screws 5.

The lower part 4 has a longitudinal socket in its free end guarded byset-screw 9 to receive and hold a needle or othersuitable stylus 10adapted to play lateral wave records.

On the other hand, 11 is a stylus adapted to play vertical waverecords,.ii-, being located in a transversely extending socket formed inthe back of the lower stylus-bar part 4,}said socket being guarded by aset-. screw 19;.

In the. enlarged view Fig. 4, the socket for the lateral-wave stylus isdesignated 13 and that for the vertical wave stylus is designated 14. Itwill be seen that they are transverse to each other but not in the sameplane, so that their socket endscan cross each other and thereby provideample seats for the styli in the part 4 without unduly enlarging orthickenmg it.

Figs. 5 and 6 show a modification wherein the thumb or set-screw 8 isreplaced byan ordinary screw 88 which permanently secures the parts 44"and 44 together. The

part 44" is the same as the part 4". in the preceding figures exceptthat it carries a longitudinally yielding detent pin 44 in-f; tended tospring into one or the other of the What I claim is 1. A sound-box,provided with a stylusbar having a part furnished with two separatestylus sockets, one for lateral wave records and the other for verticalwave records; said part being adjustable relatively to the sound-box tobring a stylus in either socket into position for cooperation with arecord suitable to it.

'2. A sound-box, provided with a stylusbar having an end-part furnishedwith two separate stylus sockets, one for lateral wave records and theother for vertical wave records; said end-part being pivotablerelatively to the sound-box to bring a'stylus in either socketintoposition for cooperation with a record suitable to it.

3. A sound-box, provided with a stylusbar having an end-part furnishedwith two separate stylus sockets, one for lateral wave records and theother for vertical wave records; said end-part being pivotablerelatively to the sound-box to bring a stylus in either socket intoposition for cooperation with a record suitable to it; and releasablelocking means for securing said end-part rigid-1y to the main part ofthe stylus-bar inits different pivotal positions.

4. A sound-box comprising a stylus-bar whose lower part carries twostyli for lateral and vertical wave records respectively, said lowerpart being pivotable relatively to theupper part of said stylus-bar intodifferent playing positions suitable for playing the respective kinds ofrecords with the respective styli adapted thereto, the stylus-barbeingpivotally supported on the sound-box, the pivotal axis ofsaidsupport coinciding with the axis of the, pivotal connection betweenthe lower and upper parts of said bar.

5. A sound-box comprising a casing, a diaphragm, and a stylus barpivotally supported on the casing and comprising parts which are pivotalrelatively to each other, the pivotal axis of said parts on each otherand of said upper part, and means, on said lower part for holding alateral wave record stylus projecting in continuation of the free-end ofsaid lower part, and for holding a vertical-wave record stylusprojecting transversely from the back of said lower part.

7 A sound-box comprising a casing, a diaphragm, and a stylus barpivotally supported on the casing and comprising parts which are pivotalrelatively to each other, one of said parts being connected to thediaphragm, and the other being the stylus bearing part, said last namedpart having two pivotal positions of adjustment for playing respectivelylateral and vertical wave records without changing the position of thebox, and two styli positioned on said part to be respectively broughtinto play by said pivotal adjustment of said part.

8. A sound-box comprising a casing, a diaphragm, and a stylus barpivotally supported on the casing and comprising parts which are pivotalrelatively to each other, one of said parts being connected to thediaphragm,

and the other being the stylus bearing part, said last named part havingtwo pivotal positions of adjustment for playing respectively lateral andvertical wave records without changing the position of the box, and twostyli positioned on said part to be respectively brought into plav bvsaid pivotal adjustment of said part; and locking means for securingrigidly together the two parts of the stylus-bar in their said differentpositions of relative pivotal adjustment.

9. A sound-box, provided with a stylusbar having an end-part furnishedwith two separate stylus holders occupying a permanent position relativeto each other, one for lateral wave records and the other for verticalwave records; said end-part being adjustable relatively to the main partof the stylus-bar to bring either holder into playing position.

10. A sound-box provided with a stylus bar having an end-part furnishedwith two separate stylus sockets permanently disposed in angularrelation to each other, one for lateral wave records and the other forvertical wave records; said lower part being adjustable relatively tothe main part of the stylusbar to bring a stylus in either socket intoposition for cooperation with a record suitable to it.

In testimony whereof, I have signed my name to this specification, this28 day of July, 1915.

RICHARD JAMES PRETTIE.
